SSO, WinAD and Design Studio Client

Hello,

I've some trouble to implement Single-Sign-On for the Design Studio Client application. If I check the Option Single-Sign-On [X] Enabled in the logon screen, I'll get the following error message:

An exception occured during Single-Sign-On:

java.lang.ClassCastException: org.ietf.jgss.GSSException cannot be cast to [B...

See the documentation for Single-Sign-On using Kerberos.

So far, I've added the following two lines to the Analysis.ini file, which is located in the root folder of the Design Studio client:

-Djava.security.auth.login.config=C:\Windows\bscLogin.conf

-Djava.security.krb5.conf=C:\Windows\krb5.ini

The bscLogin.conf contains the following lines:

sap.bo.dsws.client {

com.sun.security.auth.module.Krb5LoginModule required

debug=true

useTicketCache=true;

};

Is there something else missing?

Is it possible to trace the SSO authentication?

Best Regards,

Alex
